I am currently trying to present and hopefully sell EZ-robots to schools in the middle east. We have been using the robots for 3 months now and we go to different meetings and demonstrations with the robots to gain some attention.
But we have a problem: Burned out servos. At the moment we are having troubles with 5-6 different servos. They simply stop working or snap in the middle of movements. Last time we were at a demo, JD's arm suddenly broke and went the wrong way during a pushup script. We immediatly replaced the servo with another one, but now the problem is that SIX is only working as spare-parts.
I would like to know if some of you guys are facing the same problem with burned out servos? we have tried to open up a few of them, to check for mistakes and on one of them, the chip is melted.
On two of the others, the motor is working just fine when we connect it to 6V batteries, but they don't move when connected to the chip, even though nothing appear to be wrong.
On the last 2-3 nothing happens, so we suspect that the motors are burned out.
To me it just seems too fast with these burn-outs, because if we are selling them to schools, they should be working for a long time.
Kind regards, Benjamin
